C99 gas configury

Also remove alloca stuff since we don't use alloca in gas nowadays.

	* configure.ac: Don't check for string.h, strings.h, stdlib.h,
	errno.h, limits.h, locale.h or time.h.  Don't check for unlink,
	remove, sbrk (unused) or setlocale.  Adjust gas_test_headers.
	Don't check for errno, free, malloc, realoc, sbrk, strstr, getenv
	strstr, or vsnprintf declarations.
	(AC_ISC_POSIX, AC_FUNC_ALLOCA, AC_C_INLINE): Don't invoke.
	* as.h: Don't include alloca-conf.h, include config.h instead.
	Include string.h, stdlib.h, errno.h unconditionally.  Remove
	various fallback declarations.
	* asintl.h: Don't test HAVE_LOCALE_H.
	* as.c: Don't test HAVE_SETLOCALE.
	* dwarf2dbg.c: Include limits.h unconditionally.
	* expr.c: Likewise.
	* sb.c: Likewise.
	* symbols.c: Likewise.
	* config/tc-cr16.c: Likewise.
	* config/tc-d30v.c: Likewise.
	* config/tc-i386.c: Likewise.
	* config/tc-ia64.c: Likewise.
	* config/tc-tic54x.c (tic54x_mlib): Call remove rather than unlink.
	* config.in: Regenerate.
	* configure: Regenerate.
	* Makefile.in: Regenerate.
	* doc/Makefile.in: Regenerate.
